VLM1/VLM1B User Manual 18
USB Operation
The VLM1/VLM1B can also be controlled via a serial command from a computer’s USB port
(configured as a virtual COM port). A USB cable is included with the controller. Once the device is
connected to a computer (or USB Hub*), in most instances, the driver for the USB interface will be
installed. If this connection does not occur, a USB driver program can be downloaded from:
http://www.ftdichip.com/Drivers/CDM/CDM%20v2.12.04%20WHQL%20Certified.exe
This USB driver is also included on the Flash Drive which is included with your VLM1/VLM1B
controller. In fact, in addition to the link above, the USB driver can be found on the same Flash Drive
that this PDF User Manual is located – This user manual is also available for download at
www.uniblitz.com .
(*Each VLM1/VLM1 unit connected to a USB Hub will require a minimum of 0.5A each for
operation.)
Once communication is established, the shutter can be commanded to the open state by sending the
ASCII ”@” symbol. The shutter will close by sending a capital “A” symbol. See USB Commands in the
“External Input Characteristics”.
Testing the communication can be accomplished with a terminal emulation program such as Termite
3.1, found at
http://www.compuphase.com/software_termite.htm . (Termite 3.1 is copyrighted software
that is free for personal and commercial use. You may use it and distribute it without limitations. You
may however not remove or conceal the copyright. There are no guarantees or warranties whatsoever;
use it at your own risk.)
Maintenance
Proper care and maintenance of the VLM1/VLM1B should be taken as with any sensitive electronic
instrument.
There are no user-serviceable parts on the
VLM1/VLM1B . The +5VDC input on the PWR/COM
connector and the Shutter Fuse on SHUTTER connector Pin#1 are resettable.
It is highly recommended that if a problem is suspected with the unit that it be returned to the factory for
checkout, proper adjustments, and calibration. Failure to do this may damage the unit’s circuitry and/or
functionality and will void the factory warranty.
Inspection
Inspect the VLM1/VLM1B for damage, wear, and missing parts. If the unit appears to show signs of
damage, it should be checked thoroughly to verify correct operation and performance. If damage is
suspected, please return the unit to the factory for repair – there are no user-serviceable parts on the
board.
